Destinations are now either on the red list or not.
If they're not, then people who are fully vaccinated, and those under 18, won't need to do a pre-departure lateral flow test or a day-8 post-arrival test.

He says the old system was one of the most "complicated, expensive and stressful" in the continent.
The new system eliminates "orange countries" and is the first step is dismantling the traffic light system in the UK.
